RDA, AIX, Perl and ulimit 1

This entry was posted in AIX Oracle RDA on by

The Metalink analyst kept insisting that the “ulimit -d” value was too low.
Running an RDA for Oracle on AIX today I saw that the ulimit values were different if I run on command line or through perl:

$perl -e 'system("ulimit -a");'
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         2097152
stack(kbytes)        unlimited
memory(kbytes)       unlimited
coredump(blocks)     unlimited
nofiles(descriptors) 2000
threads(per process) unlimited
processes(per user)  unlimited

$ulimit -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 2000
pipe size          (512 bytes, -p) 64
stack size            (kbytes, -s) unlimited
cpu time             (seconds, -t) unlimited
max user processes            (-u) 2048
virtual memory        (kbytes, -v) unlimited
